To all whom it may concern; a v Be it known that I, vi aurus V. Jo' i q'sor'r, residing at Bloomsburg, Pennsylvania, and" being a citizen of the United States, have invented certain new and useful Improvements in Mine-Car Vheels; of which the following is a ,full, clear, and exact descrip-X tion, such as will enable others" skillediin .the art to which it appertains to make and use-the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though 7 it is to be' understood that the invention is not limited to the exact details of construetion shown and described, as it is obvious thatvarious modifications thereof will occur to persons skilled in the/art, a In said, drawing. Figure 1 isa vertical transverse section through my improved WllBEl', its associated journal-beariiw and an adjacent portion of the car-anddisclosesthe improved roller-bearing assembly in place in the wheel. Fig. 2 is an elevational view of that end of the roller-bearing assembly adjacent the reduced portion of the axle; andFig. 3 is an elevational view of the other end, of the roller-bearing assembly. a y This invention relates to, new and useful improvement in mine cars and comprises certain. features of novelty in the detail for mation and assembly thereof, as will be hereinafter pointed out. a ()ne of the objects oi the invention is-to, provide a roller bearing for a, car or other vehicle,.which is of the self-contained type and which may be-placedin the Wheel in an assembled condi'tion and removedufor "dis assembly or repairs at the will of the operator and Whiclnin the preferred form, provides also a bearing toranend portion of I an axle extended Within .the Wheel, the

Wheelhub beingipreferably of the closed, end typeand providing a bearing forthe end of. said axle.

- Cooperating with the Wheel'there is shoivn a journal box of the general type commonly employed in mine cars, into which journal box'the inner end of the heelflhubis pro 1: jected, and surrounding the Wheel hub there is. provided a packing tot-prevent wasteful egress of lubrica'nt.-

considerable quantity 1 lorlcant will remain he iippl edt the interior ii-centricity is due to ordinary faults n1 from. the movement of the wheel in operation back and forth longitudinally of the axle will not eject lubricant from the interior of the wheel as it would if the end 5 portion of the axle at 7 were. of the same diameter as at6. Kloiiperating with the bearing annulus 15, but at the opposite end of the sleeve 12, there is provided a flanged annulus 1b which is held in position-by flange 14:.hereinbefore referred to, and rollers 21, comprising the bearing rollers, aresdpported 'by the portions 6 and 20, when the wheel is removed from its axle. The roller bear '15 ing assembly may be assembled and then slipped i'nto position within the wheel hub, after which the wheel may beplaced upon theaxle and locked in position by the linch pin8..'; g

' vide against'loss" of lubricant at theinner end. of the wheel hub, the journal bearingf. is provided within its flanged portion"31','with an annular packing 32,

whichis locked'in position by being seated .25.:inlthepacking recess 33, and said packing 32-,bears against the outer perimeter ofthe inner endof the wheel; hub 2.

It has-beenthe practice to.

. 'sortofza packinglwithin the ournal boxes i so jemployed in mine carsbut heretofore such paekingf has been of little value due tojthe ;factth a t the portion 2-of ;the-wheel hub is not a -true 1circle' concentric with the longi- :;tudinal axis-of the .axle. .The "resultant ec casting the wheel hubs and to rovide, against fsuch eccentricityJ-the. whee hub, at least the. portion '2' thereof which fits into l --.the packing ring 32-,- is-preferabl trued so Ig'as to provide a relatively tight tbetween the wheel hub portion indicated and said ackin thereb ainin .the eatest- .eifi p y g gr means extending through said axle locking ciencyinservlce'. Should t become necessary or desirable at any time to remove the roller bearing assembly' from I the wheel hub, this may be j done after the wheel has been removed from the axleby merely pressing against the- 7 shoulder 35,, which results from thecentral bore of the bearing annulus 15, .being' of less diameter than the-counterbore 5 in the.

. outer end ofthewheelhub.

The roller bearing assembly is held 'in ositionwithinthe wheel, while the wheel "8.5:: 1s held on 1 the axle by a linch pm 8, by

"'reason of theshouIder of the axle at 7 bearing against the annulus .15, conse-' quently the linch pin 8 must be withdrawn fand the wheel removed from ."thef axle be so fore the roller bearing assembly. can-be movedffroiirthe wheel-hub.--

To prevent .strain which. might. result; from sudden movement of the. wheel longiig tudinallyof the axle, the iunerfacejofflth closed {end a 3 is, preferably .archedias shown:

rovide some ;With the axle wall.

at 36, thereby providing a bearing for the. end of the axle admirably adapted to receive end thrusts due to serviceconditions.

The rollers, the sleeve and the means employed to hold the rollers .in position in the sleeve are all removable as an assembled unit in the event of the wheel being broken or worn out and are capable of use in other wheels than the one illustrated,

The chamber 9 and the-chamber receiving the roller bearing assembly are separated by means ofthe wall 40 which is preferably cast integral with the hub of the wheel and disposed as shown intermediate the inner and outer ends of saidhub, thereby pro- 80 viding a bearing for the outer end of the roller bearing assembly'at one side, and for the linch pin which cooperates with the axle as before described to hold the wheel in position on'such axle. a

While in the preferred embodiment of the diflerentlyproportioned and the shoulder at the end of the enlarged portion of the axle may bear against the member 15 and said member .15 in turn bear against thewall 40, thereby forming a stop which will prevent excessive movement of .the wheel longitudinally of the axle, at the same time relieving the hub cap portion of such stresses as are incident to service conditions. What I claim is:

.1. In combination in a mine car, a car body, a journal box in cooperative relation therewith, an axle extended through said journal box,a wheel in part rotatable in said journal box, a fixed wall integral with the outer end portion of the hub of said wheel, a roller bearing in said hub and said roller bearing in position.

- 2. In combination in a mine car wheel, a hub portion closed at one end there being a fixed wall integral with said hub intermediate its ends, an axle extending through one end of'the hub past said wall and a roller bearing locked in position in said hub by means cooperating with said-axle on One side of said wall;

3.- In combination in a wheel, a cast metal hub having an integral perforated wall intermediate the ends of said hub, an axle projected through said wall, a roller hearing held in position by said axle on one sideof the. wall and locking means coiiperating on the opposite side of'said 4.- In combinationin a hub, a per- "forated ;wall intermediate the ends of said --hub,11a"rollerjbearing removably positioned .:at,..one:;s'side;.ef said well, arr-axle projected jtlirough the wall,}-there being. ai shoulder on closed hub cap integral. with the hub and a perforated wall integral with the. hub intermediate its ends the perforation .in said wall being adapted to receive an axle and an axle of two diameters within said hub por-.

tion .adapted to cooperate with the roller bearing therein.

6. In combination in a wheel, a hub cast as an integer and-comprising a roller bearing chamber, a locking pin receiving chamber, a perforated Wall separating said chambers and an axle extending through the perforation into both of said chambers and being provided with a shouldered portion adapted to hold a roller bearing assembly in, position against longitudinal displacement.

7. In combination in a wheel assembly, a cast metal hub divided by a wall intermediate its ends into two chambers, a roller bearing assembly in one chamber, an axle bearing longitudinally against an element of said roller bearing assembly and extending through said wall and means in the other chamber cooperating with the axle to lock the wheel to the axle and to secure the roller bearing assembly within the wheel hub.

8. In combination in a mine car, a car body, a journal box in cooperative relation therewith, an axle extended through said journal box, a wheel having a hub portion cast as an integer including a portion rotatable in said journal box and being provided with an integral wall intermediate the ends of said hub, a roller bearing in said hub, a bearing annulus inserted in the hub in proximity to said Wall and cooperating with the bearing rollers and means extendingthrough said axle locking said roller bearing in position.
